THE COST OF GETTING COLD CHAIN WRONG
A single excursion can void a shipment, trigger an audit, or compromise a patient.
- Up to 25% of pharmaceutical losses worldwide are attributed to temperature failures.
- Manual log spreadsheets fail FDA 21 CFR Part 11 audit requirements.
- Last-mile blind spots cause vaccine wastage in remote sites.
